Defecting Saab owner here, apologies..
Saab 9-3 with the same 2.2 diesel as fitted to the late model omega's.
It has suddenly devleoped a serious coolant leak from the vicinity of the bottom pulley, its dry above and i'm stumped.
My thoughts where that the only coolant in this area is internally in the water jackets in the block - hence my theory of a cracked block.
Given you chaps are more knowledgeable in this motor than the saab types appear to be - help or ideas would be appreciated, as a motor change is looking likely

unfortunatley..
cheers in advance
